wrong src assignment in style.php

In line 255 of style.php
I saw this statement:
if (!isset($imgs[$img]))

{ $img_data = &$img_array[$img]; $imgsrc = ($img_data['image_lang'] ? $img_data['image_lang'] . '/' : '') . $img_data['image_filename']; $imgs[$img] = array( 'src' => $phpbb_root_path . 'styles/' . $theme['imageset_path'] . '/imageset/' . $imgsrc, 'width' => $img_data['image_width'], 'height' => $img_data['image_height'], ); }

The 'src' assignment is wrong! It does point to the file on the server, and is not generating the url. The more important problem with this is, that it exposes the servers root path.
This should be fixed by assigning a general available url_root or something like this.
